Subject [jira] Commented: (HDFS-1473) Refactor storage management into separate classes than fsimage file reading/writing
Date Sun, 28 Nov 2010 21:43:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12964595#action_12964595

Eli Collins commented on HDFS-1473:
-----------------------------------

+1

I'll commit this to trunk and branch 22 to minimize deltas since HDFS-1073 and other patches
for 22 depend on this.

> Currently the FSImage class is responsible both for storage management (eg moving around
files, tracking file names, the VERSION file, etc) as well as for the actual serialization
and deserialization of the "fsimage" file within the storage directory.
> I'd like to refactor the loading and saving code into new classes. This will make testing
easier and also make the major changes in HDFS-1073 easier to understand.
